In contrast to these, the focus of FEDn is to provide a production-grade and framework agnostic distributed implementation with a strong focus on scalability and robustness both for cross-silo and cross-device scenarios. In this respect, the work most closely related to ours is the architecture proposed in [1]}, where the authors seek to provide load-balancing capabilities through replication of local servers (with a similar role as combiners in our terminology). However, to the best of our knowledge no open source implementation associated with the work is available, and the study does not cover the large model updates that we consider here.
